Show of dominance?

[victorb17]

We bought two hens today and introduce them in to the flock. The current head hen immediately went crazy. The video shows some of this. Once thing I noticed is that her wings were down really far. Is this a sign of dominance? Or Impending fight? What ended up happening is they fought and the little young hen won. The large older hen tried to get away and was dragging the other because she wouldn't let go of some feathers! If I didn't see it with my own eyes, I wouldn't of believed the little one won!

Only obvious conflict almost leading to blows involved cockerel / stag and one of the smaller females. Dominant hen (large dark bird) was giving vocal threats and held her tail and hackles as if dominant.

It happens when the pecking order is disrupted. All should settle down in a few days. You can try adding apple cider vinegar to their water of you think they need it. It helps with the stress
